Infiniti SUV recall marks latest chapter in Takata airbag saga

Automotive parts maker Takata is having a rough year with millions of vehicles equipped with its airbag inflators being recalled. However, it looks like there might still be problems with the company's quality control, if a new recall by Infiniti is any indication.
The Japanese luxury brand is recalling 1,912 total units of the 2013 Infiniti QX56 and 2014 QX80 in North America because of a manufacturing flaw with their Takata-supplied inflators for the driver's side front airbag. Of those, 1,848 are in the United States, according to the National Highway Traffic Safety Administration. Specifically, the outer baffle could be the wrong component and cause too much pressure to build up inside. According to documents submitted to NHTSA, it's possible in a crash for the part to rupture spraying metal shrapnel at occupants. At this time, Infiniti has not had any reports of this actually happening to drivers.
While this problem sounds nearly identical to the issue affecting millions of earlier vehicles, it must be noted that this is a different fault. According to the notice being sent to dealers on NHTSA's website: "This particular Voluntary Safety Recall Campaign is unrelated to two earlier campaigns that involved Takata passenger front air bag inflators on some older model Infiniti vehicles. This issue involves a much newer inflator and is a different, more isolated, Takata quality control issue."

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

Infiniti Q60 Concept paints a pretty picture of the brand's future

Infiniti's final teaser for the Q60 Concept may have given away the shape of the curvy coupe ahead of its debut at the 2015 Detroit Auto Show, but that's not necessarily such a tragedy for this model because the design has so many subtle touches. The more you look at it, the more cool details and ornate lines you notice. What initially looks fairly simple up front belies a multitude of fascinating details, including the F1-inspired lower air dam and the subtle fin at the tip of the hood. The design around the C-pillar may be complicated but is also attractive thanks to the confluence of design from the rear fender arch, beltline and crescent-shaped cutout in the window. The concept's interior also takes a minimalist approach. It's predominantly covered in cream leather and features sports seats in quilted leather. A mix of Alcantara and carbon fiber trim are able to show off the concept's performance intentions, though. Meanwhile the glass roof makes sitting behind the wheel feel airy and inviting. Underneath, the Q60 Concept's arching hood is the company's conceptual 3.0-liter, twin-turbocharged V6 and a seven-speed automatic. Infiniti promises the production of the mill is coming in the next two years. The big question is whether the mix of sharp edges and flowing lines on the Q60 Concept really see production without too much alternation. Infiniti plans to unveil the production version next year. Until then, check out how the model appears now on the floor of the Detroit show.
